Laminates Product Details

Features & Benefits

  • Ideal for use as a cap liner or gasket in applications requiring high purity and exceptional chemical resistance
  • Easily cut to size and customizable in specific shapes and geometries
  • Available in widths from 0.625” to 12”
  • Chemically resistant films available
  • Breathable liners allow for off-gassing to prevent bursting or failures 
  • Sustainable, fluoropolymer alternative barrier films available while maintaining high-performance chemical resistance 

Typical Applications

  • Chemical Packaging: Engineered to provide superior chemical resistance and ensure reliable packaging for aggressive substances. Our PT300 venting liner regulates internal pressure by allowing gas exchange, preventing container distortion, leakage, or failure due to pressure build-up. Available in various formats to accommodate different closure types and for use with a wide range of hazardous and volatile chemicals, these liners enhance the integrity of chemical packaging, reducing the risk of spills or contamination during storage and transport.
  • Pharmaceutical Packaging: Saint-Gobain PT500 liner material provides a highly inert barrier, making it ideal for applications that demand the highest levels of purity and protection. Engineered for compatibility with sensitive formulations, this liner maintains product integrity by preventing contamination, leaching, or chemical interaction.
  • Versatile Packaging: Our PT100 cap liner material offers a cost-effective sealing solution for a wide range of applications. Designed for flexibility, it delivers excellent chemical resistance while maintaining a secure seal across various container types. It can be easily press-fit or glued into caps, providing reliable performance in both automated and manual packaging processes.
  • Medical & Pharmaceutical: Our ultra-pure liner materials, including platinum-cured silicone, offer exceptional biocompatibility and can withstand ethylene oxide (EtO) sterilization and autoclave processing without compromising integrity. Assembly and packaging in a controlled white room environment is available, minimizing contamination risks and maintaining product purity.
